Bear in mind there something a bit different about the electronics on these - some buffering or other. Don't know if that changes anything as far as your plans go.
One of my favourite fretless P things is to solo the P pickup and play right over the board at the neck joint. Lovely.
Problem with Hackett’s band is - IMO - they’ve hoyed the baby out with the bathwater.
His recent original stuff has been - again IMO - dreadful prog-by-numbers.
(Still a big Hackett fan, believe it or not)
There’s a South American lot who are astonishing as well.
Last time I saw SH (and I’ve seen him a lot) his version of IKWIL made me sick up in my mouth a little bit. Wretched.
